SUMMARY «Weather Report» applet crashes Plasma shell when user removes it. STEPS TO REPRODUCE 1. Add «Weather Report» applet to the desktop. 2. Configure it to use some location provided by «BBC Weather», e.g. Kazan' city. 3. Apply and wait for weather data to be downloaded. 4. Remove the applet. (Press and hold it for a second to enter Edit Mode, then click Remove on the floating vertical panel). 5. A popup appears prompting user to Undo the removal. 6. Cancel the prompt by closing the popup with an X button. OBSERVED RESULT Plasma goes down, and — thanks to kded magic — restarts anew. EXPECTED RESULT Welp, shouldn't crash. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.24.80 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 Kernel Version: 5.16.15-arch1-1 (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-6700HQ CPU @ 2.60GHz Memory: 15.6 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 970M/PCIe/SSE2 ADDITIONAL INFORMATION Backtrace posted on GitLab: https://invent.kde.org/-/snippets/2116 PS the whole issue may sound like "don't try to get rid of me — I'll take your Plasma session" :)
While trying to reproduce it with current git master, I can't even make the weather widget appear at all when I try to add it to the desktop. It's just... nothing happens at all. :/
> I can't even make the weather widget appear at all when I try to add it to the desktop. It's just... nothing happens at all. :/ Welp, looking out of the window still works for local weater, I guess. For those who aren't living in a bunker, at least. ((Totally broken for ukrainian usecase, gotta fix asap \s))
